ASRock are using a fully featured UEFI bios on the Extreme9 motherboard which caused us a few issues with high speed 2,400mhz memory until we received the latest 1.92 beta bios which was only released in the last week. This cured stability and the post problems as can be seen above.
The advanced and H/W monitor panels offer a wide range of settings which are fairly self explanatory. Chassis fans and the SB fan can be adjusted to suit in the H/W monitor panel.
The boot menu offers the usual list of settings to adjust boot and hard drive priority.
The other panels offer generalised settings, such as reverting to a set of default options.
The earlier versions of the bios didn’t work with the 2,400mhz XMP profiles of our Corsair and GSkill memory, failing to post. When we updated to the newest version of the bios, all 2,400mhz we have at hand worked fine.
A selection of the overclocking settings are available in a separate panel and we had no problems getting the 3960X Extreme Edition to 4.8ghz when paired up with the Corsair H100 Liquid cooler. Voltage was set to 1.47 and CPU load line calibration set to level 1. We do prefer the bios of the Asus Rampage IV Extreme, but the ASrock implementation is intuitive and stable.
